## Flat trackpad, suddenly not
Modern trackpads sit flush. If yours starts lifting like something is pressing from below, or the glass cracks, that is a warning sign and not a cosmetic quirk.

## What goes wrong inside
Laptop lithium-ion cells are safe in normal use. Overcharge or physically damage one and the chemical reactions inside start producing gas.
## The battery sits right there
On most laptops, including MacBooks and Surface models, the battery lives directly under the trackpad. Swelling cells have nowhere to expand except up through it.

> Apple already had to launch replacement programs for MacBooks with swollen batteries
## Fire is the real risk
A dead laptop is the mild outcome. A swollen battery can rupture and burn, so a loose trackpad is worth checking even if a stray screw or a drop could explain it.

> The risk of it bursting into flames is very real
## Shut it down, hand it over
Turn the laptop off and unplug it. One wrong move while prying at a swollen cell can start a fire, so let a repair shop do the work.
## What a fix costs
A new battery usually snaps the trackpad back into place. Apple charges $149 to $249 depending on model, and most makers repair a bad battery free under warranty.
## Key takeaway

If your trackpad bulges or your case looks warped, power the laptop down, unplug it, and take it to a repair shop instead of using it.
